Eccentric designer Betsey Johnson walked the aisle of the Hamptons Luxury Liner on Sunday afternoon like it was her catwalk. The fun-loving fashion icon “restlessly hopped around her seat like a bunny” while sporting a pink shirt with a sparkly blue Playboy emblem. “She boarded in East Hampton, got off and reboarded at all three Manhattan-bound stops,” a spy said. After three exits and entrances, Johnson settled down next to pocket square designer Justin Ross Lee of Pretentious Pocket. According to Lee, Johnson told him, “You’ll never make it as a fashion icon until you’ve failed at least once.”
